The AR-5381u is an 802.11n (300Mbps) wireless ADSL2+ router. AR-5381u has four 10/100 Base-T Ethernet ports, a Wi-Fi switch button and one USB Host, which supports 3G USB dongle. The router provides WAN throughput of up to 24Mbps.

The integrated AP supports WEP and WPA/WPA2 wireless encryption and 802.1x authentication. It is WDS compatible and uses WMM (QoS) to prioritize the traffic over the network. A WPS button allows for easy wireless security configuration.

This router provides VPN pass-through for IPSec, L2TP and PPTP. It features a built-in firewall to protect the network from malicious attacks.

None of the specifications state what radio frequency(s) are used for the wireless. It has been working, and my daughter and son-in-law can even use their phones on it, but I expect to see on the device a frequency and mode specification. I am a licensed radio operator, and I know that the FCC requires some such notification. Where is it?

As with all 802.11g and 802.11n devices, the RF operating frequency is the same (you can just look up the specs for allowed power levels).

802.11b, 802.11g, and 802.11n-2.4 utilize the 2.400 – 2.500 GHz spectrum. The 2.4 GHz band is divided into 14 channels spaced 5 MHz apart, beginning with channel 1 which is centered on 2.412 GHz. Channels 12-14 have additional restrictions and are not available in the US.

I have a model AR-5381u supplied by my local telephone company. I know that this company has set up the router per their own requirements but, my own monitoring software InSSIDer 4 shows the fastest data rate transfer as 144.4 Mbps and yet the spec. sheet shows 300Mbps.
Why the difference and is this spec. selectable ?
